You need to differentiate cumulative time from function time. The numbers on the left correspond to time actually consumed in this function. Cumulative includes both time consumed in this function, plus time consumed in all subfunctions.
So, in this case, FeatureClassToFeatureClass
called a lambda function 3 times, but otherwise did very little. The lambda itself took ~72s per call, for 3 calls, for a total of ~216s. It didn't call anybody else, so its cumulative time is roughly equal to its cum time. The FeatureClassToFeatureClass
function did not do much itself, so its total time is nearly zero. However, since it called the lambda function 3 times, and that function was long-running, its cumulative time is high.
